Patented Jan. 5, 1932 UNITED STATES PATENT OFFICE ROBERT W. A. BREWER, FJENKINTOWN, PENNSYLVANIA Application filed May 23,

My invention relates to a novel construction of manifolding system forinternal combustion engines, wherein I effect in a novel manner thedistribution of the explosive mixture to banks of cylinders remote fromone another and supplied by one central carbureter or by a multiplicityof carburetors.

To the above ends, my invention consists of a novel substantially rin-shaped inani-' fold or arrangement of passages positioned sagesurrounding the crank case and supplied with explosive vapour. a

It further consists of a novel collocation of a crank case, amanifolding system surrounding said crank case, and a novel ar- 5rangement of junctions therefor.

For the purpose of illustrating my inven tion I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrument alities of which my invention consists can be variouslyarranged and organized and that my invenr tion is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

In the drawings:

Fig. 1, represents a side elevation of a manifolding system embodying myinvention;

Fig. 2, represents a side elevation of Fig. 1, view-ed from the oppositeside;

' Fig. 3, represents on an enlarged scale a d vertical section on line3-3 of Fig. 1, certain parts being shown in elevation.

Referring to the drawings, 1 designates an internal combustion enginecomprising more than one bank of cylinders and having a body or block 2equipped with my novel 1930. Serial No. 454,948.

manifolding system, wherein 3 designates the centrally disposed crankshaft bearing 'for the crank shaft 4, to the end 5 of which thepropeller is secured. The engine portrayed in the present instance is ofthe eight cylinder type having four upper cylinders 6 opposed to fourlower cylinders 7, but the number of cylinders can obviously beincreased if desired. The carbureter 8 conducts the fuel into thechamber 9, which leads into the horizontal and vertical passages 10 and11. The passage 10 leads into the chamber 12 which discharges throughthe upright passage 13 into the manifold 14, which discharges at thepoints 15 into the upper bank of cylinders 6. 16 designates a verticalpassage leading from the chamber 12 to the chamber 17 from which thehorizontal passage 18 leads to the chamber 19, into which the verticalpassage 11 also discharges. 20 designates a passage leading from thechamber 19 to the manifold 21, which discharges at the points into thelower bank of cylinders 7. The chambers 12 and 17 are closed by theplates 23 and 24 respectively, and the chamber 19 is closed by the plate25. The chamber 17 is also accessible through the bottom plate 26, andthe chamber 9 is accessible through the top plate 27.

It will be seen from the foregoing that I am enabled to effect asuitable distribution of the explosive mixture to banks of cylindersremote from one another, and supplied by one central carburetor or amultiplicity of carburetors, by a substantially ring-shaped manifold ofsymmetrical design composed of the passages 10, 11, 18, and 16 and theirconnecting chambers or junctions, positioned around the crank case, andin the ease of the eight cylinder engine, being provided with fourjunctions at either one of which locations explosive mixtures can be fedinto the ring.

My novel arrangement further provides a very convenient means for localheating if desired by passing the vapour passages through the crank caseor for the fitting of a vaporizer operated by exhaust heat. It willfurther be apparent that the banks of cylinders are symmetricallydisposed adjacent to the crank case and that the inlet manifolds thevarious elements hereinbefore referred to,

' be symmetrically arranged with respect to the banks of cyhnders and toeach other, all

of which I have accomplished by my novel devices. Having thus describedmy invention, what I claim as new and desire to secure by LettersPatent, is:

1. In a manifolding system for internal combustion engines, a crankcase, a continuous ring-shaped passage for the explosive mixturesurrounding said crank case, and a plurality of junctions for saidpassage at each one of which junctions means are provided for attachingexplosive mixture introducing means.

thereto, inlet manifolds attached to opposite sides of said cylinders, aring-shaped passage for the explosive mixture surrounding sald crankcase, a. plurality of symmetrically arranged junctions in said passage,closures for said junctions, and oppositely located symmetricallyarranged connections leading from opposite junctions to said manifolds.

In an internal combustion engine, com- -means at said openings for theadmission of air and local fuel.
